International Asteroid Day

Asteroid Day (also known as International Asteroid Day) is an annual global event that aims to raise awareness about asteroids and what can be done to protect the Earth, its families, communities, and future generations.

Asteroid Day is held on the anniversary of the June 30, 1908 Siberian Tunguska event, the most harmful known asteroid-related event on Earth in recent history.

The United Nations has proclaimed that Asteroid Day will be observed globally on June 30 every year in its resolution.

Asteroid Day was officially launched on December 3, 2014.
